Abstract

The invention relates to an intelligent evacuation system and method used in a subway station fire. A fire alarm module discovers a fire and transmits fire information, a fire source positioning module positions a fire source according to the collected picture information and smoke information of the fire, an indoor pedestrian positioning module positions pedestrians in a subway station; a relay control module is connected with the fire alarm module, the fire source positioning module and the indoor pedestrian positioning module, and the relay control module combines fire information, fire source positioning information and pedestrian positioning information; and a master control module is connected with the relay control module, and the master control module plans a dynamic escape route for each pedestrian according to the combined information, pedestrian information collected by a subway APP and pedestrian information collected by a map management system, and generates an escape route guide map.
